The machine is intelligent to the extent that its actions can be expected to achieve its objectives, right?
And there are lots of systems we've built.
So when you use your GPS navigation in your car, you say, you know, you take me to the airport, you know, it figures out the best route to get to the airport.
So you're providing the objective and it's providing the solution.
We write chess programs, we basically tell the chess program what checkmate is, and then it figures out how to play the game.
So this notion is very, very powerful, that we specify objectives and then we create this sort of optimal machinery for achieving objectives and off it goes.
And the problem is, what if you put in the wrong objective?
And there are dozens of well-known examples in the history of AI where people have done exactly this.
And so since football is on my mind, having just watched England win their opening game, let's take an example from football.
So people wanted to train simulated robots to play football or soccer, and they want to give a training signal, right?
So they say, okay, we'll give a little reward.
every time a player takes possession of the ball.
Right?
Sounds good.
Okay?
So what does the program learn to do?
It learns to stand next to the ball and vibrate at very high speed.
So it's taking possession of the ball and then relinquishing possession and then taking possession like 30 times a second.
And so it's getting enormous amount of reward by basically vibrating next to the ball.
So then we see, oh, yeah, that was a mistake.
